Explode an array + add start and end tags?

Hi!

Here's my problem.

How do I explode (or another technique?) an array so I can add every item start and end tags?

Code:

$items = array('item1', 'item2', 'item3', 'item4');

Each those item should print like this:

Code:

<li>item1</li>
<li>item2</li>
<li>item3</li>
<li>item4</li>

This might be little noobie question, thanks for all help!

Something like this should do the trick for you:

php Code:

<?php
    foreach($items as $item) {
        echo '<li>'.$item.'</li>'."\n";
    }
?>

-- or depending on the style you use

php Code:

<?php
    foreach($items as $item) {
        echo "<li>$item</li>\n";
    }
?>

But either should work for you

Wow - That was fast!!

Thanks for code, that does the job! It's so clear now how to do it... ;)

Right place - right time I suppose...

No problem!

Or you could do what I did:

PHP Code:


			
echo '<li>'.implode('</li><li>', $items).'</li>';

It's all a stylistic preference. I don't actually know if this is any faster.

or:

PHP Code:


			
array_walk($items, create_function('$s', 'echo \'<li>\'.$s.\'</li>\';'));

although i wouldn't advise it personally.

With the newer versions of PHP (5.3 I think) it's also possible to do:

PHP Code:


			
$items = array('item1', 'item2', 'item3', 'item4');

array_walk($items, function($item){
    echo '<li>', $item, '</li>', PHP_EOL;
});

Yep proper lambda functions, cant wait for PHP5.3 although why on earth would they want to add a GOTO statement?.
